I have a question for those {sed, grep, awk, tr} wizards out there.
I'd like to change all the occurrences in a file of a line like this:
#include "dira\dirb\incl.h"
to
#include "dira/dirb/incl.h"
but only for the lines that begin with "#include".
As you may have guessed, I am porting a PC-DOS program to Unix.
thanks,
Ramon

For a real edit-job use a real editor :-)
script
------
ed - $1 <<@
g/^#include/s/\\\/\\//g
w
@
Invoke this script as: "script prog.c" and it will do the job.
You can run it without having to worry about creating
temporary files, wich you would need with any of the filters
you mentioned.
Have fun,
